An audit of instrumental vaginal delivery in Aminu Kano Teaching Hospital, Kano
Context: Operative vaginal delivery is used to shorten the second stage of labour
Objective: The aim of this study is to determine the incidence of instrumental vaginal deliveries in a large teaching hospital.
Study design and setting: Descriptive study involving 354 women, who either had forceps or vacuum operative vaginal deliveries including maternal and fetal outcome.
Results: One thousand two hundred and thirty three deliveries were recorded during the study period. Of this, 354 had operative vaginal delivery giving an incidence of 28.7%. Most of the patients who had either forceps or vacuum delivery were between the age of 14 – 19 years and 215 were also primigravidas. The commonest indication for both procedures was delay in second stage and fetal distress. 47.2% of the babies
delivered by forceps had fifth minute apgar score >6. 16.4% of babies delivered by vacuum had fifth minute Apgar score > 6. Fifty-Five patients had forceps delivery, while 299 patients were delivered using vacuum extractor. The major complication in the forceps group was Vesico-vaginal fistula and third degree perineal tear in the vacuum.
Conclusion: The commonest indication for instrumental vaginal delivery is delay in second stage. Most of the patients are young primigravidas. Despite the high incidence of operative vaginal delivery in this series, we recorded low morbidity.
